Scripting.

Now obviously scripting is an important part of movie making as the original vision of the movie comes from it. If you want to script a movie you have to decide what the story line is about, the order in which the scenes are played out and of course the characteristics of the different people in the film.
In this sense, you are a lot like a director.

In a lot of amateur movies, however, scripting is either just an out line or sometimes not done at all and instead the story is improvised. If you want a more relaxed approach to movie making, look out for my guide to improvisation.

So, scripting is all about creating the first image of the movie. It is a beginning guide for the actors and allows them to know what their characters are really like. It also lets the director begin to plan out it's vision.

The first thing you need to do in a script is describe the moment the scene is written in. You have to give some background info before writing out what the action and drama in the scene is, otherwise the actors will have very little idea what is going in the scene and may end up displaying the wrong emotions. This is normally something like this:

(ronald stands centre scene, arms raised preparing for the battle. jacky has just been involved with her moment of madness and is ready to enter behind camera. the scene is in an abandoned street that is slightly darker than it should be for the time of day and there is no plant life)

Then you need to write out the speech of the scene, including tone of voice, action and consequence throughout. This is normally something like this:

Ronald:(under his breath) they're coming for me.(turns around)

(jacky enters into the shot)

Ronald:(louder) and I suppose you still think this is all fun and games

Jacky: (soothingly yet slightly apprehensive) Ronald, don't worry. I've seen the destruction for my self. I know what this war is doing.

(Ronald steps forward)

Ronald: It's too late now, after all your (air quotes) inspiration (air quotes) we're now running into our end and theirs nothing we can do about it.

Remember that the making of a script isn't just about making sure the story makes sense on screen and in the minds of the actors but about developing the characters as well. As a writer you have to ensure the characters are all relatable and memorable for the right reasons compared to their part in the story. For example, making the main character a small and unimportant character that develops throughout the movie is a perfect character whilst an evil villain would be better developed as a shadowy figure and someone unlikable. 

In the end the script is all about creating the scene on paper and getting a good idea of the whole story out before the actors create something more physical. Although the script can be quite often changed, it is one of the most important parts of a successful movie and is the first impression of the over all film.
